I sold my car, and bought an electric cycle this year, and I'm pretty impressed with it. I commute on it - charge it overnight once or twice a week, and don't get a sweat up even on hills into a head wind. Costs $5 per year to charge it, and $12 to insure it. Compared to my car it's ridiculously cheap - and because most of the time I'm passing cars that are waiting for other cars ahead, I get to work in around the same time as a car (12 minutes by bike. When there's no traffic I can do it 10 minutes in a car, but a normal morning is 15-20 minutes).
I've seen those tuk-tuk's around where a bike pulls a carriage and takes a couple of people in the back. All you need is a carriage on it and a bigger motor and you could go anywhere in the city on it all weather, but to be honest it's not too hot to wear rain gear on the bike anyway as you aren't working, the battery is.
I had to go out of town on a bus instead, but cost about the same as petrol for the trip would have or maybe even cheaper.
Not quite the same freedom as having a car, but at less than 10% of the cost, I'm happy enough.
I would say that within 3 years, at least 30% of the population will move to electric simply because of the cost. And I think it will be bikes not cars that show the biggest growth.
